hi
always trying to find the best jetting for my 2003 bullet...
the configuration is: short bottle, TM32 with Ace canister.
the best setting for the pilot jet is 25 and 1-3/4 turns out on the air screw... starts easily, even cold..
i had to use shims on the (P4 jet) needle because the 3rd position from the bottom is too cold and 2nd from the bottom is too rich...
so the best position i found is 2.75 (2nd position plus a 3/4 shims), great pull, nice brown plug.
But... they don't work well together... when i have 25 pilot jet and 2.75 needle positon, i have a hole just after the idle throttle position before the needle comes into action... not a big deal but annoying when rev slowly with a low throttle...
i tried to enrich the needle position, 2.5 needle position and 2.25 needle position, the hole disapears at 2.25 but i'm too rich, black and suity plug...
i also tried to put a 27.5 pilot jet but the screw is a little off at 2.5 turns out... and now starting the engine cold is not easy... it takes a douzain kicks often helped with electric start...
i kept this last try... the only drawback is to cold start...
any other idea?? throttle valve cutaway? mine is stock...
are they available??
